Description

Technical Field

[0001] The present disclosure relates generally to electric utility grids. More specifically, the present disclosure relates to distributed communications and control for electric utility grids.

Background

[0002] There has been an increasing emphasis in recent years on energy conservation. Electric utilities have also come under increasing pressure to reduce the need to fire up polluting power plants to serve peak demands, such as during hot summer days. Two ways in which utilities can perform these tasks are referred to as demand side management and supply side management. Demand side management refers to the selective reduction of energy demand in response to peak loading conditions. For examples, utilities install devices in the homes of participating consumers that, under utility control, selectively disable energy consuming devices (for example, hot water heaters or air conditioning units) in response to peak loading conditions. As another example, distributed energy resources provide a significant resource for addressing peak loading conditions, in shifting or modulating loads, as well as generation on the distribution network. However, current utility services infrastructure lacks provisioning and flexibility for managing a large number of distributed energy resources particularly where these resources are connected behind the customer meter. Therefore, it would be advantageous to provide more sophisticated control mechanisms to permit electric utilities and others to effectively monitor and control distributed energy resources.

Summary

[0003] One aspect of the disclosure provides a method of transmitting and receiving data from a client device of a utility. The method includes receiving, by a proxy controller associated with a residence, data from a client device located in the residence over a second network. The client device comprises one or more of an energy consuming appliance and a distributed energy resource connected to a utility. The method further includes processing, by the proxy controller, the received data. Processing the data includes aggregating the received data in a predefined format. The method further includes storing, by the proxy controller, the aggregated data within the proxy controller. The method further includes sending, by the proxy controller, the aggregated data to a central controller over a first network.

[0004] Another aspect of the disclosure provides a system of communicating data to and between a client device in a residence and a utility network. The system includes a proxy controller located at the residence and a first network configured to transmit and receive data between a central controller associated with the utility network and the proxy controller. The system further includes a second network configured to transmit and receive data between the proxy controller and the client device in the residence. The proxy controller is operative to receive one or more notifications from the central controller over the first network, process the one or more notifications, generate one or more message based on the one or more notifications, and send the one or more message to the client device over the second network.

[0005] Yet another aspect of the disclosure provides a system of communicating data to and between a client device in a residence and a utility network. The system includes a proxy controller located at the residence and a first network configured to transmit and receive data between a central controller associated with the utility network and the proxy controller. The system further includes a second network configured to transmit and receive data between the proxy controller and the client device in the residence. The proxy controller is operative to receive data from the client device over the second network, aggregate the received data in a predefined format, store the aggregated data within the proxy controller, and send the aggregated data to a central controller over the first network.

Detail Description

[0007] Reference will now be made in detail to exemplary aspects of the present disclosure that are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like structure.

[0008] Utilities generally deploy a central control server, also referred to as a central controller, to manage and control the activities of a wide array of disparate client devices while adhering to preferences and individualized energy usage patterns of the premises in which those client devices are deployed. The client devices may be widely distributed across a large service area and interconnected via a range of available communications means. In addition, the client devices can be associated with different manufacturers and vendors that provide differing control capabilities as well as differing service agreements with service vendors and premise owners. To support scalability, the central controller may need to be capable of interacting with an increasing number and array of client devices. However, increasing scalability may require greater processing and communications infrastructure to allow the central controller to aggregate, interact and control larger numbers of client devices.

[0009] In addition to increased information state storage maintenance, there is a consequent increase in communications and centralized processing resources to manage and control an increased number of client devices. Implementing service control algorithms at the central controller becomes increasingly challenging where the central controller is to directly understand and manage the capabilities of the individual client devices as part of a joint system optimization and where close, frequent, and individually-customized device communications may be desired for control of the client devices. As the number of client devices and the time interval of controls increase, it becomes increasingly difficult to deliver optimized system control.

[0010] The disclosure provides an ability to distribute the problem by aggregating the client devices under distributed edge controllers, also referred to as proxy controllers, while maintaining overall centralized control coordination. For example, the disclosure provides communications and control architecture that minimizes and reduces redundant wide-area coordination and control data communications exchanges between a central controller and a distributed set of client devices. The disclosed communications and control architecture creates a system hierarchy in which the client devices communicate with localized proxy controllers. The proxy controllers filter, compress, and aggregate the control exchanges between the central controller and client devices. The proxy controllers can locally process activity and operating energy patterns of the client devices by performing, for example, localized, high-frequency meter data processing without the need to communicate that fine-grained data to the central controller. The proxy controllers can also locally collect and process information received with high frequency from the client devices without the need to communicate that detailed information to the central controller. In addition, the proxy controllers can use locally derived or collected information in its local control decision-making while providing aggregated data summaries that allow the central controller to manage arrays of client devices distributed across the extended population of end customer premises.

[0011] The disclosed two-level hierarchical control and communication system creates scalable and effective services control by distributing the functions of the central controller into distributed proxy controllers that are moved to the edge of the utility network and where the proxy controllers directly interact with a much smaller subset of the total population of client devices. The two-level control system allows the central controller interactions with client devices to be reduced since specific as well as full function communications and control exchanges take place only between the proxy controllers and the subset of client devices that each proxy controller is responsible for.

[0012] In certain examples, the proxy controllers are able to aggregate the information exchanged with the central controller and, therefore, minimize the communications and control interactions that flow from the central controller to the client devices at the edge of the utility system. The proxy controllers interact and coordinate with the central controller from which they are controlled. The proxy controllers, on behalf of the central controller, implement and engage in the communications and control interactions of the client devices or client control devices that control the client devices. Additionally, by coordinating the activity of a much smaller subset of the client devices that may have a shared local domain, the proxy controllers support further optimized local control within an edge domain while still being able to represent and reflect the control directives of the central controller. The proxy controllers support the local control in concert with the localized end-customer preferences and associated usage load or generation patterns of the client devices.

[0013] In examples, the disclosed hierarchical communications and control architecture, in addition to providing more efficient scalability as a number of proxy controllers grows, also supports a wide variety of heterogeneous communications capabilities between the central controller and the proxy controllers at the interface of the local edge domains. Because there is no direct communications interactions between the central controller and the client devices, the central controller is able to filter, group, and aggregate control commands to the proxy controllers. The proxy controllers then support the more specific and involved communications and control interactions that individual client devices require, on behalf of the central controller. In the case of specific communications and control protocols, such as, Institute of Electrical and Electronics Engineers (IEEE) 2030.5 used for Distributed Energy Resources (DER), each proxy controllers can implement and represent the actions of a standard server in interactions with standard client devices. Another protocol, Modbus, is an example of the one of many standard protocols that may be used for communications between the proxy controller and DERs over the one of many wireless or wired local premise networks. This enhances system interoperability and expandability by allowing standardized client devices to be integrated into the overall control system. Each client device is able to interact and communicate with a proxy controller in a consistent and transparent manner just as it would if there were a singular central controller.

[0014] Figure 1 illustrates an example communications and control architecture 100 in accordance with example embodiments. Communications and control architecture 100, for example, is a hierarchical distributed control structure to maximize utilization of DERs. As shown in Figure 1, communications and control architecture 100 includes a central controller 102, a first network 104, an alternate first network 140, and a plurality of residences 106 (for example, a first residence 106₁, a second residence 106₂, ..., a Nth residence 106_N).

[0015] Central controller 102 is a computer system which includes one or more processors and one or more memories. Central controller 102 also includes a database 120. Database 120 of central controller 102 stores data including, but not limited to, customer data, network topology and operating data, geographic information, metering data, and energy transaction schedules. In examples, central controller 102 receives data, e.g., prices, reliability information, weather forecast, from a wholesale market, for example, an Independent System Operator (ISO). Central controller 102 also receives data from a distribution company, a transmission company, aggregators, and customers. The processor of central controller 102 processes the received data using data stored in database 120 and then generates signals based on the processed data. The generated signals are appropriate for procurement of energy, e.g., via DER such as turning on generators, or to cause portions of aggregated electrical storage generation and/or energy resources to be coupled to the electrical grid (e.g., through inverters), thus increasing supply to the grid. The generated signals can further cause adjustment of load, e.g., via Demand Response (DR) such as temporarily reducing utility consumption by pausing charging of an electric vehicle or a storage device, turning off air conditioning units, water heaters, and other customer assets.

[0016] Central controller 102 communicates with proxy controllers 130 in plurality of residences 106 via first network 104 or alternate first network 140, or a combination thereof. In examples, first network 104 and alternate first network 140 can be any suitable network for enabling communications between various entities, such as between central controller 102 and one or more proxy controllers 130 associated with plurality of residences 106. Such a network may include, for example, a local area network, a wide-area network, a virtual private network, the Internet, an intranet, an extranet, a public switched telephone network, an infrared network, a wireless network, a wireless data network, a cellular network, or any other such wired or wireless network(s) or combination(s) thereof. First network 104 may, furthermore, incorporate any suitable network topology. First network 104 and alternate first network 140 may utilize any suitable protocol. Communication over first network 104 or alternate first network 140 may be enabled by wired or wireless connections, and combinations thereof including low-speed/capacity and high-speed/capacity network connections. In some examples, first network 104 includes a radio frequency (RF) mesh/tower network, the Internet, a fifth generation (5G) cellular network, or a combination thereof. In other examples, first network 104 is an Advanced Metering Infrastructure (AMI) network and the alternate first network 140 may be a premise end-customer owned high speed internet access network.

[0017] Plurality of residences 106 are a variety of structures or enclosures that are associated with energy consumption. The structures may span a variety of structure types, such as private residences, houses, apartments, condominiums, schools, commercial properties, single or multi-level office buildings, and/or manufacturing facilities. A number of examples described herein refer to the structure as being a private residence in the form of a house, but embodiments are not so limited as one skilled in the art would understand that the techniques described herein could equally be applicable to other types of structures. It is to be appreciated that, while some embodiments may be particularly advantageous for residential living scenarios, the scope of the present teachings is not so limited and may equally be advantageous for business environments, school environments, government building environments, sports or entertainment arenas, and so forth. Thus, while many of the descriptions below are set forth in residential living context, it is to be appreciated that this is for purposes of clarity of description and not by way of limitation.

[0018] Each of plurality of residences 106 may include a plurality of client devices, also referred to as edge devices. For example, first residence 106₁ includes a first plurality of edge devices 108₁, second residence 106₂ includes a second plurality of edge devices 108₂, ..., Nth residence 106_N includes a Nth plurality of edge devices 108_N. In examples, each of plurality of residences 106 can include a different number and a different set of client devices. For example, first plurality of edge devices 108₁ of first residence 106₁ may include loads 110₁, a Heating Ventilation and Air Conditioning (HVAC) 116₁ with connected smart thermostat 118₁, a DER resource with inverter 112₁, and a Home Energy Management System (HEMS) gateway 114₁. First residence 106₁ may also include one or more loads with a Load Control Relay (LCR). Loads 110₁ may include energy consuming devices which may not have a controller associated with them such as televisions, microwaves, home audio equipment, heating/cooling systems, laundry machines, dishwashers, etc. DER resource with inverter 110₁ may include a DER source 120₁ and a DER source controller 122₁ and an inverter 124₁.

[0019] In examples, DER source 120₁ may include electric vehicles, fuel cells, photovoltaics (PV), and energy storage devices, for example, batteries. DER source controller 122₁ may control DER source 120₁. For example, DER source controller 122₁ may connect DER source 120₁ to the electric grid for charging (that is, withdrawing power from the electric grid as a load) or for discharging (that is, providing power to the electric grid as an energy resource), or disconnect from the electric grid to be idle (that is, neither charging nor discharging).

[0020] HEMS gateway 114₁ controls other energy consumption devices in first residence 106₁. For example, first residence 106₁ may include one or more energy consumption devices, which may be electrical energy consumption devices such as televisions, microwaves, home audio equipment, heating/cooling systems, laundry machines, dishwashers, etc. Similarly, energy consumption devices could include one or more other types of energy consumption devices such as gas consumption devices. For example, first residences 106₁ may include a natural gas (air/water/etc.) heater, stove, fireplace, etc. In some examples, HEMS gateway 114₁ can include an intelligent, network connected thermostat that is operable to control the thermal environment of the residence. In examples, DER source controller 122₁, connected smart thermostat 118₁, and HEMS gateway 114₁ are also referred to as client control devices.

[0021] Second plurality of edge devices 108₂ of second residence 106₂ may include loads 110₂, a DER resource with no inverter 126₂, a DER resource with inverter 112₂, and a HEMS gateway 114₂. DER resource with no inverter 126₂ may include a DER source 136₂ and DER source controller 138₂. DER resource with no inverter 126₂ can only be used as a controllable load. DER source controller 138₂ may control DER source 136₂. For example, DER source controller 138₂ may connect DER source 136₂ to the electric grid for charging (that is, withdrawing power from the electric grid as a load) or disconnect from the electric grid to be idle (that is, neither charging nor discharging). DER resource with inverter 110₂ may include a DER source 120₂ and a DER source controller 122₂, and an inverter 124₂. In examples, DER source 120₂ may include electric vehicles, fuel cells, PV, and storage devices, for example, batteries. DER source 120₂ is connected to the electric grid through inverter 124₂. Second DER source controller 122₂ may control DER source 120₂. For example, DER source controller 122₂ may connect DER source 120₂ to the electric grid for charging or discharging, or disconnect from the electric grid to be idle. HEMS gateway 114₂ controls other energy consumption devices in second residence 106₂.

[0022] Nth plurality of edge device 108_N of Nth residence 106_N may include loads 110_N, Demand Response (DR) controllable load assets 128_N, a DER resource with inverter 112_N, and a HEMS gateway 114_N. DR controllable load assets 128_N may include energy consuming devices which can be switched on or switched off for DR events. DER resource with inverter 112_N may include a DER source 120_N, a DER source controller 122_N, and an inverter 124_N. In examples, DER source 120_N of Nth residence 106_N may include electric vehicles, fuel cells, PV, and storage devices, for example, batteries. Second DER source 120_N is connected to the electric grid through inverter 124_N. DER source controller 122_N may control DER source 120_N. For example, DER source controller 122_N may connect second DER source 120_N to the electric grid for charging or discharging, or disconnect from the electric grid to be idle. HEMS gateway 124_N controls other energy consumption devices in Nth residence 106_N.

[0023] Each of plurality of residences 106 include a proxy controller of proxy controllers 130. For example, first residence 106₁ includes a first proxy controller 130₁, second residence 106₂ includes a second proxy controller 130₂, ..., and Nth residence 106_N includes an Nth proxy controller 130_N. In examples, first proxy controller 130₁, second proxy controller 130₂, ..., and Nth proxy controller 130_N together are referred to as proxy controllers 130 or edge controllers 130. Although one proxy controller is shown to be associated with one residence, one proxy controller can be associated with more than one residence and/or more than one proxy controller can be associated with one residence. In some examples, a number of proxy controllers 130 per residence can be based on a number of client devices in the residence, an area of the residence, and/or desired granularity of control.

[0024] Each of proxy controllers 130 interacts with and controls the client devices or client control devices in a residence associated it. For example, first proxy controller 130₁ interacts with and controls first plurality of edge devices 108₁ of first residence 106₁. Similarly, second proxy controller 130₂ interacts with and controls second plurality of edge devices 108₂ of second residence 106₂ continuing to Nth proxy controller 130_N which interacts with and controls Nth plurality of edge devices 108_N of Nth residence 106_N.

[0025] Each proxy controllers 130 interacts with and controls the client devices in a residence associated it through second networks 132, for example, first second network 132₁, second network 132₂, ...., Nth second network 132_N, or through alternate second networks 134, for example, first alternate second network 134₁, second alternate second network 134₂, ...., Nth alternate second network 134_N, or a combination thereof. For example, first proxy controller 130₁ interacts with and controls first plurality of edge device 108₁ of first residence 106₁ through first second network 132₁, though first alternate second network 134₁, or a combination thereof. Similarly, second proxy controller 130₂ interacts with and controls second plurality of edge device 108₂ of second residence 106₂ through second network 132₂, though second alternate second network 134₂, or a combination thereof. Nth proxy controller 130_N interacts with and controls Nth plurality of edge device 108_N of Nth residence 106_N through Nth second network 132_N, though Nth alternate second network 134_N, or a combination thereof.

[0026] Hence, each of proxy controllers 130 can interact with and control the client devices in a residence with which it is associated through more than one network. For example, first proxy controller 130₁ can interact with and control first plurality of edge device 108₁ of first residence 106₁ through a local extension of an RF mesh AMI network as well as a premise WiFi network. In another example, first proxy controller 130₁ can interact with and control some of first plurality of edge device 108₁ of first residence 106₁ through an AMI network and some other of first plurality of edge device 108₁ of first residence 106₁ through a premise-provided combined Wide Area Network (WAN) and Local Area Network (LAN). In some examples, each of second networks 132 is based on use of IEEE 2030.5 protocol as the application control protocol over a wireless network. In some other examples, one or more of second networks 132 are based on different protocols from one another. For example, first second network 132₁ can be based on Transmission Control Protocol (TCP)/Internet Protocol (IP) wireless communications while second network 132₂ can be based on serial wired communications. The flexibility with the use of different protocols enhances communications and control architecture 100 interoperability and expandability by allowing different types of plurality of proxy controllers 106 to be integrated with the premise DR and DER devices.

[0027] Each proxy controllers 130 interacts with and controls the client devices in a residence associated with it based on information or notification received from central controller 102. For example, each proxy controllers 130 may receive information or a communication from central controller 102 over first network 104 or alternate first network 140. The information or the communication from central controller 102 can be related to a grid event, for example, a demand response event, an upcoming price adjustment event, or to cause portions of DER resources to be coupled to the electrical grid (e.g., through inverters), thus increasing supply to the grid.

[0028] The information or the communication from central controller 102 can be uniformly broadcasted message and each proxy controllers 130 may receive the same information or the communication in a same format supported by first network 104. This results in a reduction of the number of messages and amount of data required to convey the information or the communication from central controller 102 as the information or the communication from central controller 102 is provided to proxy controllers 130 that too in a uniformly broadcasted message. Central controller 102 can also communicate specific information to individual proxy controllers 130 in response to specific aggregated information received from proxy controllers 130.

[0029] Each of proxy controllers 130 can generate local messages for client devices in a residence associated it based on the information or the communication received from central controller 102. For example, for a DR event, or other grid service event, first proxy controller 106₁ can generate one or more messages for first plurality of edge device 108₁, that is, thermostat 118₁, DER source controller 122₁, HEMS gateway 114₁, and a LCR connected to a load, based on the information or the communication received from central controller 102 for the service event. For example, first proxy controller 106₁ can generate a command for DER resource 122₁ to dispatch energy from DER source 120₁ to the grid. In another example, first proxy controller 106₁ can generate a command for thermostat 118₁ to adjust temperature setting of the premise.

[0030] The messages generated by proxy controllers 130 can be based on a format or a protocol associated with second networks 132 connecting each of proxy controllers 106 with the client devices in the residence associated it. For examples, first proxy controller 106₁ can generate one or more messages for each of first plurality of edge devices 108₁ based on IEEE 2030.5 protocol supported by first second network 132₁. Thus, proxy controllers 130 can translate messages between different formats.

[0031] In addition, each of proxy controllers 130 can receive information from the client devices in a residence associated it. For example, first proxy controller 130₁ can receive one or more messages from one or more of first plurality of edge device 108₁, that is, thermostat 118₁, DER resource 112₁, and HEMS gateway 114₁ regarding a current power consumption rate, a current power generation rate, a remaining charge, a current temperature, a current efficiency, etc. First proxy controller 130₁ can receive the one or more messages for first plurality of edge devices 108₁ through first second network 132₁ or first alternate second network 134₁.

[0032] Each proxy controllers 130 can process the received information from the client devices in a residence associated it. For example, first proxy controller 130₁ can process the information received each of thermostat 118₁, DER resource 112₁, HEMS gateway 114₁, and a LCR. In addition, first proxy controller 130₁ can receive energy consumption data for first plurality of edge device 108₁ and process the received energy consumption data. The processing of received information can be controlled by central controller 102. For example, central controller 102 may provide with a format for processing and storing the information received from plurality of edge devices 108. Each of proxy controllers 130 can then send the processed information to central controller 102 through first network 104 or alternate first network 140. In addition, each of plurality proxy controllers 130 can control response to a DR event or a grid event by the client devices based on processing of the received information from the client devices in a residence associated it. For example, based on the processing of the consumption data received from a premise energy metering device and a DR event received from central controller 104, first proxy controller 130₁ can generate load control messages to one or more thermostat 118₁, DER source controller 122₁, and HEMS gateway 114₁ to comply with the DR event.

[0033] Such processing of the information by proxy controllers 130, including information that may be locally derived through processing of high-frequency electric meter-reading, can reduce processing load on central controller 102. In addition, such processing of the information by proxy controllers 130 can reduce the amount of data being sent back to central controller 102. This may lead to overall increased efficiency. Additionally, by coordinating the activity of a much smaller subset of the client devices that may have a shared local domain, each of proxy controllers 130 supports further optimized local control within the edge domain while still being able to represent and reflect the control directives of central controller 102. In examples, each of proxy controllers 130 can be located in a meter device of a residence associated with it and can include a processor and a memory.

[0034] In examples, the elements of communications and control architecture 100 may be practiced in hardware and/or in software (including firmware, resident software, micro-code, etc.) or in any other circuits or systems. The elements of communications and control architecture 100 may be practiced in electrical circuits comprising discrete electronic elements, packaged or integrated electronic chips containing logic gates, a circuit utilizing a microprocessor, or on a single chip containing electronic elements or microprocessors. Furthermore, the elements of communications and control architecture 100 may also be practiced using other technologies capable of performing logical operations such as, for example, AND, OR, and NOT, including but not limited to, mechanical, optical, fluidic, and quantum technologies. As described in greater detail below with respect to Figure 3, the elements of communications and control architecture 100 may be practiced in a computing device 300.

[0035] Figure 2 is a flow diagram setting forth the general stages involved in a method 200 consistent with an embodiment of the disclosure for transmitting and receiving data from a client device of a utility. Method 200 may be implemented using proxy controllers 130 as described in more detail above with respect to Figure. However, embodiments of the disclosure may be implemented by any computing device, for example, a computing device 300 as described in greater detail in Figure 3 below. Furthermore, method 200 may be performed anywhere, for example, at home plurality of residence 106s or on in the cloud. Ways to implement the stages of method 200 will be described in greater detail below.

[0036] At block 210 of method 200, one or more of proxy controllers 130 associated with a residence 106 receives data from a client device located in the residence over second networks 132 or alternate second networks 134. The client device can include one or more of an energy consuming appliance and a distributed energy resource connected to the electric grid. For example, first proxy controller 130₁ can receive consumption data from first plurality of edge devices 108₁ associated with first residence 106₁ over first second network 132₁ or first alternate second network 134₁. First proxy controller 130₁ can receive consumption data for first plurality of edge devices 108₁ associated with first residence 106₁ from an energy metering device associated with first residence 106₁.

[0037] At block 220 of method 200, proxy controllers 130 can process the received data. Processing the data can include aggregating the received data in a predefined format. For example, first proxy controller 130₁ can process the received consumption data for first plurality of edge devices 108₁ associated with first residence 106₁. Processing can include aggregating the consumption data to determine a load pattern or to create a consumption profile of first plurality of edge devices 108₁. In some examples, the aggregation is performed in a format dictated by central controller 102.

[0038] At block 230 of method 200, proxy controllers 130 can store the aggregated data within proxy controllers 130. For example, first proxy controller 130₁ can store the aggregated consumption data of first plurality of edge devices 108₁ on a storage on first proxy controller 130₁.

[0039] At block 240 of method 200, proxy controllers 130 can send the aggregated data to central controller 102 over first network 104, alternate first network 140, or a combination thereof. For example, first proxy controller 130₁ can send the stored aggregated consumption data of first plurality of edge devices 108₁ to central controller 102 over first network 104, alternate first network 140, or a combination thereof. In some examples, first proxy controller 130₁ can anonymize the aggregated consumption data before sending to central controller 102. This can enhance privacy and security of first residences 106₁.

[0040] By processing and aggregating of the data at proxy controllers 130, a load of central controller 102 is reduced. In addition, the processing and aggregating of the data at proxy controllers 130 leads to a reduction in the amount of data to be transferred from proxy controllers 130 to central controller 102. Moreover, the processing and aggregating of the data at proxy controllers 130 leads to a reduction in the amount of memory needed at central controller 102 to store the consumption date for the client devices.

[0041] In some examples, proxy controllers 130 are further operative to receive one or more notifications from central controller 102 over first network 104 or alternate first network 140 from central controller 102. For example, proxy controllers 130 can receive a DR event notification or a price change notification from central controller 102.
